Over one hundred years ago as McMaster-Carr was first opening its doors there were very few automobiles and no airplanes, plastics or computers. Our history has coincided with developments such as mass production, the Great Depression, two world wars, the growth of the aerospace industry, computers, and the Internet.

More than a century later we’ve grown from a small Chicago operation selling products locally to a network of five facilities in Chicago, IL; Los Angeles, CA; Atlanta, GA; Cleveland, OH; and Princeton, NJ that serve customers all over the world. We offer hundreds of thousands of items including fasteners, pumps, casters, and raw materials.

Operating now with the benefit of modern facilities and technology, we find ourselves focused on the same activities that made us successful in the beginning…adding products to our catalog that will help our customers keep their operations running, making purchasing simple, and delivering products quickly.
